extreme-MACHINE.

To'all whom it mag concern:

. Be it known that I, JOSIAH E. SYMONS, acitizen of the United States, residing at Chicago, in the'county of Cook and State of Illinois, have invented a certain new and useful Improvement in Crushing-Machines, of which the following a specification;

My invention relates to improvements in crushing machines and is illustrated in the accompanying drawings, wherein Figure 1 is a part section on an enlarged scale; Fig. 2 a section ,uong the line 2-2 of Fig. 1.

Like parts'are indicated by like letters in both the figures.

The shaft A which carries-the driving pulley A is mounted .in the bearings A, A,

upon the frame A, and is held from longitudinal -motion therein by the collars A and carries at one end the member B, which is provided with the spherical bearing surface 13 The cylinder or hollow shaft G is mounted upon the hollow shaft 0 by means of the roller bearing C. and has at one end the flange C from which project the lugs C whichcarry the collar C threaded at G to engage the socket C which is adapted to engage the spherical surface B The frame A is rovided with the grooves D, -D ,'and slots l concentric with the ball and socket bearin The bearings A A are provided with t e lugs D to engage the slots D, D. The shaft A may be rotated about the center of the ball and socket bearing to vary the angle which it makeswith the shaft *0. When this is done the-lugs D will ride in the grooves D and the bolts D in the 'shaft C slots D.

F The crushing surface E is mounted upon the member B and held thereto by means of the centrally located screw E The crushin' surface E is mounted upon the flange and held thereto by means of the peri herally located bo ts E. The downwar ly depending foot y is mounted upon the frame F, carries the shaft C and affords a bearing for the -.shaft F upon which is mounted the Ipulley F which supports the conveyer belt material being-fed to the crushmg, surfaces from the belt through the It will be evident that while I have illustrajted inmy drawings an operative form ofj'device, numerous changes could be made insizeyahapesnd arrangement of the parts without do artiaig materially fromtbe spirit I Specification of Letters Patent.

are as follows :In my crushing machine ofmy invention. 1 Wish, therefore, 1 IlgS be considered to a certain degree I have two crushing members rota-ting in opposition one :to the other, and mounted on separate shafts. One of these shafts is posi-, tively driven, the other is frictionally driven from the first shaft. I provide means for varyingthe angle of obliquity of the crushing members, these means operative by a bodily angular displacement of one of the shafts, The ball and socket joint connection interposed between the shafts permits this displacement without hindering the driving ofthe machine.- I provide one of the crushing members mounted upon a hollow shaft and means for feeding thermaterial to be crushed through said holl'ow shaft to the crushing space.

I claim 1. A crushing machine comprising two opposed rotatingcrushing members at an angle one with the other the distance between said members increasing from their peripheries inwardly at all points therealong, one of said crushing members mount-- ed upon a hollow shaft, the other upon a solidlshaft, said shafts located upon opposite sides of the crushing members.

2. A crushing machine comprising two opposed rotating crushing members at an angle one with the other, supporting shafts at either side of said members and a ball and socket joint interposed between said shafts.

3. 'A crushing machine comprising two opposed rotating crushing members one of them provided with a feed opening therethrough and at an angle one with the other and; rotating in the same direction, one of said members mounted upon a fixed hollow shaft, the other upon an angularly adjust able shaft, said shafts extending in opposite directions.

4. A crushing machine comprising two opposed rotating crushing members one of them provided with a feed opening therethrough and at an angle one .with the other, and rotating in the same direction, one of said members mounted upon a hollow shaft, the other upon an 'angularly adfu's'tother, the distance between said members increasing from their peri heries inwardly, and feeding means for said tive through one of said members, said means including a shaft, said members rotating in the same direction.

22. A crushing machine comprising two opposed rotating crushing members an larly adjustable one to the other the fi s tance between said members increasing from their peripheries inwardly, and feeding {)neans operative through one of said memel's.

23. A crushing machine comprising two opposed rotating crushing members at an angle one with the other, shafts at either side of said members, a ball and socket joint interposed between said shafts, means for adjusting the angularity of said shafts comprising bearings wherein one of said shafts is mounted, a support for said bearing, a lug upon said bearing, and a groove in said support concentric with the ball and socket joint in which said lug rides.

24. A crushing machine comprising a shaft, a member having a hemispherical surface mounted on said shaft, a hollow shaft in opposition to said shaft, a connection between said hollow shaft and said hemispherical surface, a crushing surface mounted upon said hemispherical surface and a crushing surface mounted upon said hollow shaft.

25. A crushing machine comprisingtwo opposed crushing members at an angle one with the other the, distance between said members increasing from their peripheries inwardly, one of said crushing members mounted upon a hollow shaft, the other upon a solid shaft, said shafts located upon machine opera- 7 o posite sides of the crushing members one 0 said members being dish-shaped.

26. A crushing machine comprising a plurality of opposed rotating crushing members, the distance between them increasing from their peripheries inwardly, said members inclined one to the other, shafts upon which they are mounted projecting in opposite directions, and means for varying the distance between said members.

27. A crushin fixed rotatable sfi ber carried thereby, a dish-shaped crushing member in opposition thereto and a ball and socketconnection between said members, a hollow shaft supporting said dishshaped member.

28. A crushing machine comprising a fixed rotatable shaft, a fiat crushing member carried thereby, a dish-shaped crushing member in opposition thereto and a ball and socket connection between said members, a hollow shaft supporting said dish-shaped member, and a fixed shaft upon which said shaft rotates and aball and socket joint interposed between said supporting shafts.

29. A crushing machine comprising two opposed rotating disk-like crushing members at an angle to each other and with an open crushing chamber between them, two opposed shaft-s extending in opposite directions and upon which the disks are respectively mounted, one of said disks provlded with a feed aperture therethrough.
